# FeatureConfig

> _Since v1.24.0_

Declarative feature configuration interface.

This interface is intentionally empty in core — it is populated via **module augmentation**
by feature side-effect imports (`@toolbox-web/grid/features/selection`, etc.).
Third-party plugins can also augment this interface to add their own features.

#### Example

```ts
// Each feature import augments this interface:
import '@toolbox-web/grid/features/selection';
import '@toolbox-web/grid/features/filtering';

grid.gridConfig = {
  features: {
    selection: 'range',       // ← typed by selection feature module
    filtering: { debounceMs: 200 }, // ← typed by filtering feature module
  },
};
```
